A few show tricks to find slow queries in mongodb

Enable profiling

First, you have to enable profiling

> db.setProfilingLevel(1)

Now let it run for a while. It collects the slow queries ( > 100ms) into a capped collections, so queries go in and if it's full, old queries go out, so don't be surprised that it's a moving target...

Mac OS X 10.9 Mavericks

Custom recipe to get OS X 10.9 Mavericks running from scratch, setup applications and developer environment. I use this gist to keep track of the important software and steps required to have a functioning system after a semi-annual fresh install.

Install Software

The software selected is software that is "tried and true" --- software I need after any fresh install. I often install other software not listed here, but is handled in a case-by-case basis.

Install from App Store
